Acoustic attenuation device with fan modules and deflectors
A recently granted patent (Publication Number: US11867201B2) discloses an innovative acoustic attenuation device designed to reduce noise generated by fan assemblies. The device includes multiple fan modules that direct airflow in opposite directions, along with strategically placed air deflectors to control the airflow. Additionally, acoustic attenuating foam is applied to the interior surfaces of the air deflectors to further reduce noise. The foam has a thickness between 1mm and 5mm and is selected to attenuate both airflow and vibrational energy produced by the fan modules. The angled air deflector surfaces, angled between 10 to 80 degrees relative to the airflow directions, enhance the device's noise reduction capabilities.
Moreover, the patent also covers a system incorporating the acoustic attenuation device within a data storage housing containing multiple hard drives. The system includes additional acoustic attenuating foam applied to the interior surfaces of the housing to minimize noise further. The design of the system ensures that the airflow generated by the fan modules is efficiently controlled by the air deflectors and the acoustic attenuating foam, resulting in a quieter operational environment. The angled air deflector surfaces within the device and system play a crucial role in directing airflow effectively while reducing noise levels, making it a valuable innovation for noise-sensitive environments such as data centers or offices.
